Ok well so far I DJ'd 2 parties and I run into the same problem so I am gonna see what you guys have to say.
I normally start at 11 and for the 1st hour or so I play rap/R&B/old stuff, some slow beat stuff and then at 12 I step it up with a good top 10 list as well as reggaeton, and reggae as well. I will also throw in a good 1/2 hour of club stuff to make sure everyone is happy. The last 1/2 I am running dry (2am), most people come and ask me to repeat songs which I hate to do but now that they are drunk they can dance to it. Any good ideas of how you spread the music out through-out the night...?
